Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for connecting frame columns. Background Technology

[0002] Steel frames are a common structural form for modern industrial buildings. Due to factors such as processing capacity and transportation, frame beams and columns are currently manufactured in sections in the factory and then transported to the project construction site. After the first-floor frame columns and beams are assembled and connected to form the first-floor platform, the lower columns of the first-floor frame are then connected to the upper columns of the second-floor frame (generally, the connection node is about 1.3 meters above the frame platform beam to accommodate the ergonomic construction height) to extend the frame columns and subsequently erect the second-floor frame platform beams. This process is repeated to complete the erection of all the platforms at all elevations.

[0003] On-site frame column connection typically involves using a liftable work platform to carry personnel, such as the construction engineering lifting platform that can be stably connected and installed as disclosed in Chinese patent CN221370408U, or erecting a steel ladder between the frame platform beam and the frame column for high-altitude operations. However, these methods involve high-altitude operations, resulting in excessively high costs for machinery, unstable steel ladder installation that is prone to slippage and poses safety hazards, the need for multiple personnel and multiple locations to repeatedly install and then dismantle the ladders, low construction efficiency, and unstable operator positioning that affects welding quality, thereby creating structural safety hazards and hindering the smooth implementation of construction progress, quality, and safety.

[0004] Therefore, existing technologies address the aforementioned problems by using prefabricated work platforms. For example, Chinese patent CN211691387U discloses a prefabricated operating platform for steel column docking construction. Multiple triangular support frames are installed on each side wall of the steel column; these triangular support frames are detachably cantilevered and inserted into steel sockets fixedly installed on the side walls of the steel column; a platform plate is placed on the overlapping plane formed by all the triangular support frames; and a protective railing is detachably installed around the outer perimeter of the platform plate. However, this work platform is enclosed on all four sides and must be disassembled from the top. After the final capping is completed, the work platform can only be disassembled and cannot be reused. Furthermore, adding (welding or bolting) additional components to the vertical surface will cause initial damage to the steel column and affect the structural service life. Additionally, the detachable triangular support frames pose a safety risk of loosening. Utility Model Content

[0005] Therefore, in order to solve the problems in the prior art, this utility model proposes a frame column docking device that is structurally stable, easy to assemble and disassemble, and low in cost. The specific solution is as follows:

[0006] A frame column docking device is disclosed, wherein a frame beam is vertically connected to each of the four sides of the docking lower frame column, the four frame beams are located on a horizontal plane, and the docking upper frame column is located directly above the lower frame column. The frame column docking device includes: a concave groove bottom plate, vertical uprights, horizontal crossbars, and an L-shaped clamping device. The concave groove bottom plate surrounds the lower frame column and is fixed to the upper surfaces of three adjacent frame beams via the clamping device. A vertical upright is vertically fixed to the upper surface of each corner of the concave groove bottom plate. A horizontal crossbar is welded to the top of each pair of adjacent vertical uprights, and multiple horizontal crossbars are welded between adjacent vertical uprights. The concave groove bottom plate has a rectangular slot. The L-shaped clamping device consists of a vertical screw, a horizontal support rod connected to the bottom of the vertical screw, a roughened support plate fixed to the horizontal support rod, and a nut. The top of the vertical screw passes through the rectangular slot, and the nut is screwed into the top of the vertical screw.

[0007] Furthermore, the width of the groove portion of the concave groove bottom plate is greater than the width of the lower column section of the frame, and the depth of the concave groove bottom plate is greater than the height of the lower column section of the frame.

[0008] Furthermore, the vertical poles are made of steel pipes or angle steel, with a height of 1.2-1.5m, and at least two vertical poles are vertically welded to each side of the concave groove bottom plate.

[0009] Furthermore, adjacent horizontal bars located on the same plane are parallel to each other and the distance between them is less than 1m.

[0010] Furthermore, the frame column docking device contacts the upper flanges of the three frame beams below, and each of the two sides of the upper flanges of the three frame beams has two symmetrical rectangular slots.

[0011] Furthermore, the L-shaped clamping device also includes a square perforated washer located above the rectangular slot and below the nut.

[0012] The installation method of the above-mentioned frame column docking device is as follows: push the concave opening of the frame column docking device to a position tangent to the outer side of the flange plate of the lower frame column, with the bottom plate of the concave groove located on the upper surface of the upper flange plate of three adjacent frame beams; insert the vertical screw portion of multiple sets of L-shaped clamping devices into the rectangular slot, so that the upper surface of the roughened support plate is tangent to the lower surface of the upper flange plate of the frame beam; insert square perforated washers into the upper ends of the vertical screws 11 of each set of L-shaped clamping devices that extend out of the rectangular slot, and then tighten the nuts; unscrew the nuts, turn and remove the clamping devices, push and disassemble the frame column docking device, and then install the frame column docking device according to the above operation steps for docking construction at the frame column of the next axis or elevation position until the docking of the frame columns at all axis elevation positions of the project is completed.

[0013] The beneficial effects of this utility model are as follows: This frame column docking device is simple to process and manufacture, and convenient and quick to operate. It is suitable for high-altitude docking construction of frame columns of various specifications. It solves the construction problems of current docking methods, such as the safety hazards caused by unstable ladders that are prone to slippage, high cost of lifting work platforms, and the initial damage to steel columns caused by the cumbersome disassembly and insecure fixing of prefabricated work platforms. It allows workers to dock frame columns stably on the frame column docking device, ensuring safety and stability. It avoids the problem of poor docking quality and rework caused by unstable ladders or lifting platforms. Moreover, this frame column docking device is reusable and inexpensive, reducing construction costs, improving construction efficiency, ensuring the safety of workers operating at heights, ensuring the smooth implementation of construction safety, progress, and quality, and achieving the social and economic benefits of safe construction.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] In one embodiment, a frame column connection device is first fabricated, wherein a frame beam is vertically connected to each of the four sides of the lower frame column 1: frame beam I 3, frame beam II 4, frame beam III 5, and frame beam IV 6, respectively. The four frame beams are located on a horizontal plane. The frame column connection device includes a concave groove bottom plate 7, vertical uprights 8, horizontal crossbars 9, and an L-shaped clamping device. A steel plate with a relatively high rigidity and a thickness of approximately 16mm is cut and processed according to the width of the flange plates of the four frame beams to serve as the concave groove bottom plate 7, so that the concave groove bottom plate... The width of the groove portion of 7 is greater than the cross-sectional width of the lower column 1 of the frame, and the depth of the concave groove bottom plate 7 is greater than the cross-sectional height of the lower column 1 of the frame. That is, the concave groove bottom plate 7 can completely cover the three sides of the lower column 1 of the frame. A vertical pole 8 is vertically welded to the upper surface of each corner of the cut concave groove bottom plate 7. The vertical pole 8 is a steel pipe with a height of 1.2-1.5m and an outer diameter of 16-36mm, or an angle steel with a height of 1.2-1.5m. A horizontal crossbar 9 is welded to the top of each of the two adjacent vertical poles 8 to form a concave frame. Simultaneously, multiple horizontal bars 9 are welded between adjacent vertical uprights 8. The horizontal bars 9 on the same plane are parallel to each other, with equal spacing not exceeding 0.6m. At the same time, at least one additional vertical upright 8 is vertically welded on the three longest sides of the concave bottom plate outside, excluding the vertex, forming a double-loop concave-shaped protective cage mesh railing to prevent personnel from falling outwards. Two symmetrical rectangular slots 10 are opened on each of the three plates of the concave bottom plate 7. The distance between the two symmetrical rectangular slots 10 is greater than the width of the two sides of the upper flange of the corresponding contacting frame beam I, frame beam II, frame beam III, or frame beam IV. An L-shaped clamping device is constructed, consisting of a vertical screw 11, a horizontal support rod 12 horizontally connected to the bottom of the vertical screw 11, a roughened support plate 13 fixed to the horizontal support rod 12, a square perforated washer 14, and a nut 15.

[0020] The concave groove bottom plate 7 surrounds the lower column 1 of the frame and is fixed to the upper surface of the three adjacent frame beams via the clamping device.

[0021] The upper column 2 of the frame is located directly above the lower column 1 of the frame. The concave opening of the frame column docking device is pushed to a position tangent to the outer side of the flange plate of the lower column 1 of the frame. The concave groove bottom plate 7 is located on the upper surface of the upper flange plate of the three adjacent frame beams.

[0022] The frame column docking device contacts the upper flange of the three frame beams below. Each side edge of the upper flange of the three frame beams is directly opposite a rectangular slot 10. The vertical screws 11 of multiple sets of L-shaped clamping devices are inserted into the rectangular slots 10. The screws 11 are rotated so that the upper surface of the chisel support plate 13 is tangentially attached to the lower surface of the upper flange of the frame beam. Square perforated washers 14 are inserted into the upper end of the vertical screws 11 of each set of L-shaped clamping devices that extend out of the rectangular slots 10, and then the nuts 15 are tightened.

[0023] The operator enters the frame column docking device, stands and walks on the concave groove bottom plate 7 to complete the docking construction of the flanges and flanges, and webs of the lower frame column 1 and the upper frame column 2 in all directions of welding and bolting.

[0024] Unscrew nut 15, turn to remove the clamping device, push the disassembly and assembly frame column docking device, and then install the frame column docking device according to the above operation steps for docking construction at the frame column of the next axis or elevation position until the docking of frame columns at all axis and elevation positions of the project is completed.
